Hacks

I've written patches against openssh
which allow it to use gpg for the host key and for user
authentication. I'm hoping that this sort of mechanism will
eventually reduce the amount of blindly accepting ssh host keys that
invariably happens today.

I had set up a secondary mail server for the FSF; here are some
details of how it worked.
(This scheme seems is no longer be in use there.)
